D.
Data import wizard is an application that is instalied on your computer.
Answer: A C
Explanation
Option A: Developer and Developer Pro sandboxes have different storage limits.
True.
Explanation:
Developer Sandbox:
Question
#:2
Developer Pro Sandbox:
Provides 1 GB of data storage and 1 GB of file storage.
Provides 200 MB of data storage and 200 MB of file storage.
The storage limits affect how much data you can import into these environments.
A developer deployed a trigger to update the status__c of Assets related to an Account when the Account’s status changes and a nightly integration that updates Accounts in bulk has started to fail with limit failures.
What should the developer change about the code to address the failure while still having the code update all of the Assets correctly?
Add List<asset> assets = [SELECT Id, Status_c FROM Asset WHERE AccountId = :acctId) to line 14 and iterate over the assets list in the for loop on line 15.
Move all of the logic to a gueueabs class that queries for and updates the Assets and call it from the trigger.
Add a LIMIT clause to the SOQL query on line 16 to limit the number of Assets queried for an Account.
A.
Change the getAssecsTspdace method to process all Accounts in one call and call it outside of the £ox loop that starts on line 03.
Answer: D
Question #:3
A developer needs to have records with specific field values in order to test a new Apex class.
What should the developer do to ensure the data is available to the test?
Use test.loadData() and reference a JSON file in Documents.
Use Test.loadData() and reference a CSV file in a static resource.
Use Anonymous Apex to create the required data.
Use SOQL to query the org for the required data.
Answer: B
Explanation
To ensure that specific data is available in test methods, the developer should create test data within the test context.
Option B: Use Test.loadData() and reference a CSV file in a static resource.
Correct Approach.
Explanation:
Test.loadData() is a method that allows test methods to load test data from a CSV file stored as a static resource.
This method creates the records in the test context, ensuring that the data is available during the test execution.
Using a CSV file makes it easy to define multiple records with specific field values.
Usage Example:
@isTest
private class MyTestClass {
@isTest
static void testMethod() {
List<MyObject__c> testRecords = (List<MyObject__c>) Test.loadData(MyObject__c.sObjectType, 'MyTestData');
// Proceed with testing using testRecords } }
Where 'MyTestData' is the name of the static resource containing the CSV file.
Question #:4
A developer created a custom order management app that uses an Apex class. The order is represented by an Order object and an Orderltem object that has a master-detail relationship to Order. During order processing, an order may be split into multiple orders.
What should a developer do to allow their code to move some existing Orderltem records to a new Order record?
Create a junction object between OrderItem and Order.
Select the Allow reparenting option on the master-detail relationship.
Change the master-detail relationship to an external lookup relationship.
Add without sharing to the Apex class declaration.
Answer: B
Explanation
To allow moving existing OrderItem records to a new Order record in a master-detail relationship:
Option B: Select the Allow reparenting option on the master-detail relationship.
Explanation: Enabling "Allow reparenting" on the master-detail field allows child records (OrderItem) to be reparented to a different master record (Order).
Steps: Go to the master-detail field on OrderItem.
Edit the field and select "Allow reparenting".
Question #:5
A developer created a trigger on the Account object. While testing the trigger, the developer sees the error message 'Maximum trigger depth exceeded’.
What could be the possible causes?
A.
B. C.
D.
The developer does not have the correct user permission.
The trigger is too long and should be refactored into a helper class.
The trigger is getting executed multiple times.
The trigger does not have sufficient code coverage.
Answer: C
Explanation
The error message occurs when a trigger invokes itself recursively more 'Maximum trigger depth exceeded' than the allowed limit.
Option C: The trigger is getting executed multiple times.
Correct Answer.
Explanation:
Question #:6
This error indicates that the trigger is recursively calling itself.
This can happen if the trigger performs an update or insert operation that causes the same trigger to fire again, leading to an infinite loop.
Salesforce enforces a limit on the recursion depth to prevent stack overflows.
The following code snippet is executed by a Lightning web component in an environment with more than 2,000 lead records:
Which governor limit will likely be exceeded within the Apex transaction?
B. C. D.
Total number of SOQL queries issued
Total number of DML statements issued
Total number of records processed as a result of DML statements
Total number of records retrieved by SOQL queries
Answer: B
Question #:7
Which code statement includes an Apex method named updateaccounts in the class accountcontreoller for use in a Lightning web component?
import updatelccounts from '@aalesforce/apeax/AccountController': import updateiccounta from 'AccountConctroller':
import updatelccounta from ‘RAccountContraller,updateiccounta’;
import updase’Accounts from '@=salesforce/apex/AccountController ., updateaccounts’;
Answer: D
Explanation
When importing an Apex method into a Lightning Web Component (LWC), the correct syntax is:
import methodName from '@salesforce/apex/ClassName.methodName';
Option D: import updateAccounts from '@salesforce/apex/AccountController.updateaccounts';
Correct Syntax.
Explanation:
import updateAccounts:
Specifies the JavaScript function name to reference in the LWC. from '@salesforce/apex/AccountController.updateaccounts';:
Indicates that we are importing from an Apex class named AccountController, and the method is updateaccounts.
Case Sensitivity:
The class and method names are case-sensitive and should match the Apex code.
Question #:8
The Account object in an organization has a master-detail relationship to a child object called Branch. The following automations exist:
Roll-up summary fields
Custom validation rules
Duplicate rules
developer created a trigger on the Account object.
Which two things should the developer consider while testing the trigger code?
Choose 2 answers
Rollup summary fields can cause the parent record to go through Save.
The validation rules will cause the trigger to fire again,
Duplicate rules are executed once all DML operations commit to the database.
The trigger may fire multiple times during a transaction.
Answer: A D
Explanation
Option A: Roll-up summary fields can cause the parent record to go through Save. True.
When a changes, on the parent object are recalculated. child record roll-up summary fields
This causes the parent record to , which can trigger save triggers on the parent object
Question #:9
Universal Containers (UC) processes orders in Salesforce in a custom object, ord=xr <. They also allow sales reps to upload CSV files with thousands of orders at a time.
A developer is tasked with integrating orders placed in Salesforce with UC’s enterprise resource planning (ERP) system.
A.
After the status for an order__ c is first set to 'Placed’, the order information must be sent to a REST endpoint in the ERP system that can process one order at a time.
What should the developer implement to accomplish this?
Callout from an Qfuture method called from a trigger
Callout from a Batchable class called from a scheduled job
Flow with a callout from an invocable method
Callout from a Queueable class called from a trigger
Answer: D
Explanation
To integrate Order__c records with the ERP system after their status is set to 'Placed', and considering that orders may be uploaded in bulk, the developer should:
Option D: Callout from a Queueable class called from a trigger
Explanation:
Question #:10
Trigger: Implement an after-update trigger on Order__c to detect when the status changes to 'Placed'.
Queueable Apex: Use Queueable Apex to handle asynchronous processing and callouts. Queueable classes support callouts by implementing the Database.AllowsCallouts interface.
Benefits:
Handles Bulk Data: Queueable Apex can process records in batches and can be chained for processing large volumes.
Supports Callouts: Unlike future methods, Queueable Apex allows for more complex data types and supports callouts with fewer limitations.
How many Accounts will be inserted by the following block of code?
Answer: D
Explanation
Understanding the Code: for (Integer i = 0 ; i < 500; i++) {
Account a = new Account (Name='New Account ' + i); insert a; }
What the Code Does:
Loops from i = 0 to i = 499 (total of 500 iterations).
In each iteration:
Creates a new Account record with the name 'New Account ' + i.
Performs an insert DML operation for each account.
Salesforce Governor Limits:
DML Statements Limit:
Maximum of 150 DML statements per Apex transaction.
